Question

A current of 0.5A passes through a conductor for 2s. How many electrons flow through any cross section of the conductor during this interval?​

Answer 1

Answer:

6.25 x 10^18 electrons.

Explanation:

1 Ampere current is defined as flow of 6.25 x 10^18 electrons in one second, cross section of the wire is left to your choice.

0.5 Ampere current is 3.125 x 10^18 electrons flowing for one second.

For 2 seconds it is 3.125 x 10^18 x 2 = 6.25 x 10^18 electrons.
